[0027] In the above embodiment, the sub-configuration of the CSI report configuration can include resource information, thereby realizing the association between the sub-configuration and the measurement resource. Through this association, the measurement results performed by the terminal on the measurement resource can be reported using the sub-configuration, so that the terminal can perform measurement and reporting based on the sub-configuration, thereby improving the reporting efficiency of the terminal and reducing the reporting overhead of the terminal.

[0028] In combination with some embodiments of the first aspect, in some embodiments, the resource information includes: a resource list; a resource list is associated with one or more resource sets; and a resource set includes one or more measurement resources.

[0031] Based on the above solution, a resource list is associated with a resource configuration, so that the information of measurement resources contained in all resource sets associated with the sub-configuration in a resource configuration will be included in the resource list, which has the effect of simple and clear terminal parsing.

[0032] In combination with some embodiments of the first aspect, in some embodiments, a resource list is associated with a resource set with the same position index of multiple resource configurations of the CSI report configuration; wherein the multiple resource configurations include a first resource configuration and a second resource configuration; the x-th resource set associated with the first resource configuration of the CSI report configuration and the x-th resource set associated with the second resource configuration of the CSI report configuration have the same configuration position; x is the position index.

[0033] Based on the above solution, a resource list is associated with a resource set at the same configuration position of multiple resource configurations of the CSI report configuration, which has the effect of simple and clear terminal parsing.

Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0120] To reduce the power overhead of network devices, network devices can dynamically reduce the number of spatial elements or transmission power corresponding to downlink data transmission based on the dynamic changes in transmission load, thereby reducing network energy overhead. Taking into account the dynamic adjustment of spatial elements or transmission power, the spatial adaptation (SD) mode introduces CSI reporting with sub-configuration as the granularity. For the same CSI report config, it can contain L sub-configurations, each sub-configuration is associated with a specific SD pattern and / or transmission power. L can be any positive integer.

[0121] In order to improve the terminal reporting efficiency and reduce the corresponding reporting overhead, for the configured L sub-configurations, the base station can activate / deactivate N of the sub-configuration reports through relevant signaling. For semi-persistent (SP) type CSI reporting, it can be activated / deactivated through the Media Access Control (MAC) control unit (CE). In some cases, MAC CE only activates / deactivates reporting with CSI report config as the granularity. After introducing reporting with sub-configuration as the granularity, corresponding signaling needs to be designed to activate / deactivate N sub-configuration reports within L sub-configurations. At this time, the activation signaling includes downlink control information (DCI) and MAC CE.

[0122] In one embodiment, the DCI may be used to activate measurement resources. The terminal may indicate the activation state of the resource set activated in the CSI aperiodic trigger state list (CSI-AperiodicTriggerStateList) or the semi-persistent trigger state list (CSI-SemiPersistentOnPUSCH-TriggerStateList) of the physical uplink shared channel based on the CSI request field of the DCI.

[0123] In one embodiment, the CSI request field of the DCI carries a trigger state indication. The trigger state indication is used to indicate the activation state of a sub-configuration within the corresponding CSI reporting configuration. For example, a trigger state may correspond to a combination of activation and / or deactivation states of one or more sub-configurations in a resource set.

[0124] In one embodiment, for a MAC CE, the activation status of a sub-configuration within a corresponding CSI reporting configuration is indicated by a bitmap or the like.

[0125] In some embodiments, for a particular resource setting, at most one set can be activated at any one time. A maximum of three resource settings can be configured for a CSI report. If a resource setting is activated for a CSI report, the resource setting is used for channel measurement and / or interference measurement. Interference measurement is primarily used for Layer 1 Signal to Interference plus Noise Ratio (L1-SINR).

[0126] In some embodiments, the resource configuration may include but is not limited to CSI-RS resource configuration (CSI-RS resource config).

[0127] In some embodiments, if two resource settings of a CSI reporting configuration are activated, the terminal performs channel measurement based on the first resource setting and performs CSI-IM based interference measurement based on the second resource setting.

[0128] In some embodiments, if three resource settings of a CSI report configuration are activated, the terminal performs channel measurement based on the first resource setting, performs CSI-IM-based interference measurement based on the second resource setting, and performs NZP CSI-RS resource-based interference measurement based on the third resource setting.

[0129] In summary, each sub-configuration corresponds to a specific transmission power / spatial element pattern (PD / SD pattern) and is associated with part or all of the CSI resources in the activated resource set.

[0130] In some embodiments, measurement resources associated with a sub-configuration are configured based on a resource list.

[0131] In some embodiments, the CSI reporting configuration is a periodic CSI reporting configuration, and the CSI resource information is used by the terminal to determine the CSI resources for which the sub-configuration is activated, or

[0132] In some embodiments, the CSI reporting configuration is a semi-persistent CSI reporting configuration, and the CSI resource information is used by the terminal to determine the CSI resources configured in the sub-configuration.

[0133] In some embodiments, FIG1B is a schematic structural diagram of a MAC CE according to an exemplary embodiment.

[0134] The serving cell ID (Serving Cell ID) indicates the ID of the serving cell to which the MAC CE is applicable; the length of this field is 5 bits.

[0135] Bandwidth Part (BWP) ID indicates the uplink BWP applied by the MAC CE, as the code point of the Downlink Control Information DCI Bandwidth Part Indicator field specified in TS 38.212 [9]. The length of this field is 2 bits;

[0136] Si: This field indicates the activation / deactivation status of the semi-persistent CSI reporting configuration in the CSI reporting configuration (CSIReportConfigToAddModList), as specified in TS 38.331 [5].

[0137] S0 refers to the CSI reporting configuration that includes PUCCH resources for SP CSI reporting in the indicated BWP and has the smallest CSI configuration identifier (ReportConfigId) within the list whose type is set to semi-persistent ON PUSCH.

[0138] S1 refers to a reporting configuration containing PUCCH resources for SP-CSI reporting in the indicated BWP and having a second lower CSI configuration identifier (ReportConfigId), and so on.

[0139] If the number of reporting configurations in the list whose type is set to semi-persistent ON PUSCH in the indicated BWP is less than i+1, the MAC CE shall ignore the Si field.

[0140] When the Si field is set to 1, it indicates that the corresponding semi-persistent CSI reporting configuration should be activated. When the Si field is set to 0, it indicates that the corresponding semi-persistent CSI reporting configuration will be deactivated.

[0141] R: Indicates a reserved field, with the bit value set to 0.

[0172] That is, in some embodiments, the resource information can be carried in the sub-configuration in any form. In some embodiments, the resource information is carried in the sub-configuration in the form of a resource list.

[0173] In one embodiment, a CSI reporting configuration may include one or more sub-configurations. When a CSI reporting configuration includes multiple sub-configurations, some of the sub-configurations may carry resource information, or each sub-configuration may carry corresponding resource information.

[0174] In some embodiments, a CSI reporting configuration may also include a common portion, which carries parameters that are shared by all subconfigurations within the CSI reporting configuration. In this case, if a subconfiguration does not carry resource information, the CSI subreport corresponding to that subconfiguration may be reported using the measurement resources indicated by the resource information carried in the common portion.

[0175] The following examples illustrate the optional resource lists:

[0176] Method 1: Associate a resource list with a resource configuration.

[0226] In some embodiments, if a resource list is associated with multiple resource sets, all measurement resources of the multiple resource sets may be numbered sequentially, so the measurement resources of the multiple resource sets associated with a resource list may have different numbers.

[0227] In other embodiments, if a resource list is associated with multiple resource sets, the measurement resources in the multiple resource sets can be numbered to obtain position indexes. The position index of each measurement resource in the resource list corresponds to the identifier or index of the resource set.

[0306] The operation of the terminal may include at least one of the following:

[0307] When a CSI reporting configuration (CSI report config) includes multiple reporting sub-configurations (sub-configurations), the terminal uses a resource list (or CSI resource list) within the sub-configuration to determine at least one measurement resource associated with the sub-configuration. The measurement resource may include, but is not limited to, a CSI-reference signal resource (CSI-RS resource). The reference resource list may be determined based on the following method:

[0308] Method 1: Determine one or more resource sets associated with the resource list. The resource list includes the location index of the measurement resource in the application resource set or the resource ID.

[0309] A resource list is configured in a sub-configuration. This resource list applies to all resource sets configured and / or activated in the corresponding CSI report configuration.

[0310] At least one resource list is configured in a sub-configuration. The specific resource list corresponds to a specific resource setting configured and / or activated in a CSI report configuration.

[0311] At least one resource list is configured in a sub-configuration. The specific resource list corresponds to a specific resource set configured and / or activated in a CSI report configuration.

[0312] In some embodiments, the size of the resource list is equal to maxNrofNZP-CSI-RS-ResourcesPerSet. The size of the resource list here can be understood as the length of the aforementioned resource list.

[0313] In some embodiments, the size of the resource list is equal to the maximum number of CSI-RS resources included in all NZP-CSI-RS-ResourcesSets configured in the corresponding reportconfig, and / or,

[0314] In some embodiments, the size of the resource list is equal to the maximum number of measurement resources contained in the resource set of all resource sets configured in the corresponding reprotconfig (e.g., nzp-CSI-RS-ResourceSet, csi-SSB-ResourceSet, csi-IM-ResourceSet).

[0315] The resource list uses a bitmap to indicate the measurement resources associated with the application resource set, such as CSI-RS resources. In one embodiment, if the corresponding bit in the bitmap has a value of 1, the measurement resource in the corresponding resource set is associated with the sub-configuration. If the corresponding bit in the bitmap has a value of 0, the resource in the corresponding resource set is not associated with the sub-configuration.

[0316] In one embodiment, the resource list includes a location index of a measurement resource associated with the application resource set. For example, if the resource list includes a resource ID within the application resource set, and if the location index of a specific measurement resource within the resource set is included in the resource list, then the corresponding measurement resource is associated with the sub-configuration.

[0317] In some embodiments, if a location index included in a resource list is not located in the associated resource set, the terminal ignores the location index included in the resource list.

[0318] In some embodiments, if a resource identifier included in a resource list is not located in the associated resource set, the terminal ignores the resource identifier included in the resource list.

[0319] In some embodiments, the location index is an entry index of a specific measurement resource within the resource set to which it belongs. The entry index is determined based on the location index of the resource within the configuration set. The entry index here is a type of the aforementioned location index.

[0320] In some embodiments, the location index is generated by sorting all measurement resources included in the resource set within the specific measurement resource in ascending or descending order of resource identifiers, that is, the location index corresponds to the location of the measurement resource in the resource set.

[0321] In some embodiments, the resource identifier of the measurement resource is configured by RRC signaling sent by the network device.

[0322] The operations of the base station may include at least one of the following:

[0323] When a CSI report configuration includes multiple reporting sub-configurations, the base station determines at least one measurement resource associated with the sub-configuration based on the following method: The measurement resource may be a CSI-RS resource.

[0324] One or more resource sets (resource sets) applied based on signaling configuration / activation resource list. The resource set (list) includes the location index of the measurement resource in the application resource combination or the location index of the measurement resource.

[0325] A CSI resource list is configured in a sub-configuration. The resource list applies to all resource sets configured and / or activated in the corresponding CSI report configuration.

[0326] At least one resource list (CSI resource list) is configured in the sub-configuration, and a specific list corresponds to a specific resource setting configured and / or activated in the CSI report configuration.

[0327] At least one resource list (CSI resource list) is configured in the sub-configuration, and the specific resource list corresponds to the specific resource set (resource set) configured and / or activated in the CSI report configuration (CSI report config).

[0328] In some embodiments, the size of the resource list is equal to maxNrofNZP-CSI-RS-ResourcesPerSet.

[0329] In some embodiments, the size of the resource list is equal to the maximum number of CSI-RS resources included in all NZP-CSI-RS-ResourcesSets configured in the corresponding CSI report configuration.

[0330] In some embodiments, the size of the resource list is equal to the maximum number of measurement resources contained in the set of all resource combinations configured in the corresponding CSI report configuration (e.g., nzp-CSI-RS-ResourceSet, csi-SSB-ResourceSet, csi-IM-ResourceSet).

[0331] In some embodiments, the resource list indicates the measurement resources associated with the application measurement resources in a bitmap format. For example, if the bit is 1, the measurement resources in the corresponding resource set are associated with a sub-configuration, and if the bit is 0, the opposite is true.

[0332] In other embodiments, the resource list includes a location index of a measurement resource associated with an application resource set. Exemplarily, the resource list includes resource identifiers within the application resource set. If the resource identifier of a specific measurement resource within the resource set is included in the resource list, the corresponding measurement resource is associated with the sub-configuration.

[0333] In some embodiments, if a location index included in a resource list is not located in the associated resource set, the terminal ignores the location index included in the resource list.

[0334] In some embodiments, if a resource identifier included in a resource list is not located in the associated resource set, the terminal ignores the resource identifier included in the resource list.

[0335] In some embodiments, the location index is an entry index of a specific measurement resource within the resource set to which it belongs. The entry index is determined based on the location index of the resource within the configuration set. The entry index here is a type of the aforementioned location index.

[0336] In some embodiments, the location index is generated by sorting all measurement resources included in the resource set within the specific measurement resource in ascending or descending order of resource identifiers, that is, the location index corresponds to the location of the measurement resource in the resource set.

[0337] In some embodiments, the resource identifier of the measurement resource is configured by RRC signaling sent by the network device.

[0338] Assume that the terminal supports the Network Energy Saving (NES) feature and supports measurement reporting for multiple SDs (spatial patterns) and / or multiple transmit power standards. The NES feature may include support for CSI sub-reporting (sub-CSI) reporting that defines multiple sub-configurations for the same CSI report configuration.

[0339] Compared with a CSI report configuration corresponding to one CSI configuration, a CSI report configuration supporting the NES feature corresponds to multiple sub-configurations, each of which corresponds to a CSI sub-report report, which can effectively improve the dynamic CSI measurement and reporting performance.

[0340] Based on the sub-configuration corresponding resource list, the resource list can be used to indicate the associated measurement resources in the activated resource set.

[0341] Implementation 1: A resource list is included for a specific sub-configuration. The resource list indicates a resource set activated for channel measurement. The resource set may include, but is not limited to, an NZP-CSI-RS-ResourceSet, a CSI-SSB-ResourceSet, an activated CSI-IM-ResourceSet for interference measurement, and / or an activated NZP-CSI-RS-ResourceSet for interference measurement.

[0342] In some embodiments, the resource set associated with the sub-configuration resource list is one or more measurement resource sets configured for the resource configuration.

[0343] Implementation method 2: For a specific sub-configuration, at least one resource list is included. Exemplarily, the resource list included in the sub-configuration may include a first resource list, a second resource quantity list and / or a third resource list. The first resource list indicates one or more measurement resources in at least one resource set (resource set) activated for channel measurement. The resource set indicated by the first resource quantity list may include but is not limited to measurement resources associated within NZP-CSI-RS-ResourceSet, csi-SSB-ResourceSet). The second resource quantity list indicates resource resources associated within at least one CSI-IM-ResourceSet (if configured) activated for interference measurement. The third resource list indicates at least one NZP-CSI-RS-ResourceSet activated for interference measurement.

[0344] Implementation 2-1: A resource list is included for a specific sub-configuration. A resource list can be associated with resource sets in the same location as one or more resource settings. A resource setting can include one or more resource sets.

[0345] For example, the first resource list of the specific sub-configuration indicates the first resource set in the activated resource setting, the second resource list of the specific sub-configuration indicates the second resource set in the activated at least one resource setting, and so on.

[0346] The set index of the resource set is determined based on the entry index in the set list or the set ID. Specifically, the set index is determined based on the order of resource IDs from small to large or from large to small.

[0347] Implementation method 3: The size of the resource list (resource ID list) is equal to the maximum number of measurement resources that can be configured in a single resource set. For example, the size of the resource list (resource ID list) is equal to maxNrofNZP-CSI-RS-ResourcesPerSet. For example, the size of the resource list (resource ID list) is equal to the maximum number of CSI-RS resources contained in all NZP-CSI-RS-ResourcesSet configured in the corresponding report config. For another example, the size of the resource list (resource ID list) is equal to the maximum number of measurement resources contained in the set of all resource sets (e.g., nzp-CSI-RS-ResourceSet, csi-SSB-ResourceSet, csi-IM-ResourceSet) configured in the corresponding report config.

[0348] Implementation 4: The resource list uses a bitmap to indicate the measurement resources associated with the application resource set. For example, if the corresponding bit in the bitmap is 1, the measurement resources in the corresponding resource set are associated with the sub-configuration. If the corresponding bit in the bitmap is 0, the opposite is true.

[0349] The resource list includes the location index of the measurement resource associated with the application resource set. For example, if the resource list includes the resource identifier of the application resource set, and if a specific resource identifier included in the resource set is included in the resource list, then the corresponding measurement resource is associated with the sub-configuration.

[0350] Implementation 5: In some embodiments, if a location index included in a resource list is not located in the associated resource set, the terminal ignores the location index included in the resource list.

[0351] In some embodiments, if a resource identifier included in a resource list is not located in the associated resource set, the terminal ignores the resource identifier included in the resource list.

[0352] As shown in Figure 5A, the CSI report configuration includes two sub-configurations. The sub-configuration may include sub-configuration 1 (subconfig1) and sub-configuration 2 (subconfig2). A resource list (CSI resource list) is configured in each sub-configuration. The resource list (list) contains at least one location index. The size of the resource list is equal to the maximum number of configurable measurement resources in the resource set. For example, the resource list can indicate the activation status of the corresponding measurement resource (resource) in the form of a bitmap. Taking the resource list (resource list) {10110001} contained in sub-configuration 1 (subconfig 1) as an example, it indicates that the 1st, 3rd, 4th, and 8th measurement resources (resource) in the application set are in an activated state. For another example, the resource list can indicate the activation status of the corresponding measurement resource by carrying a location index. For example, as shown in Figure 5B, both sub-configuration 1 and sub-configuration 2 have configured resource sets. The resource list in the sub-configuration carries a resource identifier. If the resource index is set according to the configured position of the resource set in the CSI report configuration, the activated resource set shown in Figure 5B is set as the position index in the sub-configuration. In this case, the position index of the resource corresponding to sub-configuration 1 within the resource set is 0, 2, 3, or 7, or 1, 3, 4, 8. The position index of the resource corresponding to sub-configuration 2 within the resource set is 1, 4, 5, 6, or 2, 5, 6, 7.

[0353] When the corresponding sub-configuration is activated, the resource list configured therein applies to the resource set activated in the corresponding CSI reporting configuration. The size of the resource list is equal to the number of measurement resources contained in the resource set. If a measurement resource indicated by the resource list is not included in the resource set, the measurement resource is ignored.

[0354] Exemplarily, under the condition that CSI-AssociatedReportConfigInfo 1 is activated and subconfiguration 1 (subconfig1) is activated, the terminal performs CSI-RS measurement of subconfiguration 1 (subconfig1) based on the entry index 0, 2, 3, 7 (or 1, 3, 4, 8) in the activated NZP-CSI-RS-ResourceSet and CSI-IM-ResourceSet, that is, CSI-RS 0, 3, 5, 25 in the NZP-CSI-RS-ResourceSet, and 2, 6, 7, 20 in the CSI-IM-ResourceSet; or performs CSI measurement based on the resources with cell IDs sorted from small to large in NZP-CSI-RS-ResourceSet and CSI-IM-ResourceSet.

[0355] For example, when CSI-AssociatedReportConfigInfo 2 is activated and subconfiguration 2 (subconfig2) is activated, considering that the set configured in subconfiguration 2 (subconfig2) contains at most 2 measurement resources, the terminal only parses the first 2 elements in the resource list and ignores the information of other elements. That is, the terminal performs CSI measurement of subconfig 2 based on the activation of NZP-CSI-RS-ResourceSet1 and CSI-IM-ResourceSet and the entry index (entry index) of NZP-CSI-RS-ResourceSet2 is 1 (or 2), that is, CSI-RS 30 in NZP-CSI-RS-ResourceSet1, 10 in CSI-IM-ResourceSet and CSI-RS 3 in NZP-CSI-RS-ResourceSet2; or performs CSI measurement based on the activation of NZP-CSI-RS-ResourceSet1 and CSI-IM-ResourceSet and the resource with the cell ID sorted from small to large in 1st (or 2nd) in NZP-CSI-RS-ResourceSet2.

[0356] In this embodiment, in a scenario where the CSI reporting configuration corresponding to the NES scenario includes at least one sub-configuration, corresponding indication signaling is designed to determine the measurement resources corresponding to the sub-configuration.
